Subject: Blaze goes parallel!

Version 2.0 of the Blaze library, one of the fastest high-performance
C++ math libraries, has been released. One of the main motivations of
the Blaze 1.x releases was to provide maximum performance on a single
CPU core for all possible operations. However, the free lunch is over
[1] and today's CPUs are not single core anymore. In order to fully
utilize the performance potential of a multicore CPU, computations
have to be parallelized across all available cores of a
CPU. Therefore, starting with Blaze 2.0, the Blaze library provides
automated shared memory parallelization. Get an impression of the
possible performance boost in the Benchmarks section:

Blaze 2.0 is now available for download at

Application Webserver, which easily makes any long running C program
into a webserver allowing you to monitor the progress of your
simulation with any browser. SAWs is open source (BSD license), small,
portable and requires only a C compiler and Unix/Linux. SAWs and its

Subject: LES database for turbulent channel flow at Re_tau=590

With this post I want to promote the availability of large eddy
simulation (LES) data for the turbulent channel flow at Re_tau = 590,
following the well known DNS database of Moser, Kim and Mansour.

The database, which is available at:

has been produced within the LESinItaly initiative, an Italian
collaborative framework on LES.

Different research groups produced the results with different codes,
in particular:
- In house staggered 2nd order Finite Difference
- In house cell-centered 2nd order Finite Volume
- In house hybrid 4th order/pseudo-spectral solver
- Open-Source FV codes Code_Saturne and OpenFOAM
- Commercial FV codes Fluent and TransAT

Each group has provided results with its own SGS model(s) and a no
model computation on two separate grids (differing in the wall-normal
resolution). You can find additional information in the README files
accompanying the database.

Subject: Symbolic Numeric Computation, China, Jul 2014

We invite submissions by April 4 to SNC 2014.

The Symbolic-Numeric Computation conference series explores the rich
area of interaction between symbolic and numerical mathematical
methods. Examples of such interaction include the use of backward
error and singular value decomposition in algebraic computation. Five
earlier meetings have taken place in France, China, Canada, Japan and
the USA. The upcoming meeting will be held in Shanghai, July 28-31.

The conference web site and call for papers are available at

This year's invited speakers and their planned titles are:
- Erich L. Kaltofen, North Carolina State university, USA:

Subject: Sparse Grids and Applications, Germany, Sep 2014

The third international workshop on Sparse Grids and Applications
(SGA'14) will be held at the University of Stuttgart
September 1-5 2014.

Sparse grids are a popular approach for the numerical treatment of
high-dimensional problems. Where classical numerical discretization
schemes fail in more than three or four dimensions, sparse grids, in
their different flavors, are frequently the method of choice, be it
spatially adaptive in the hierarchical basis or via the dimensionally
adaptive combination technique.

The aim is to bring together researchers and practitioners using
sparse grids and their variants. Both theoretical and practical
aspects are highly welcome. Topics of sparse grids and their
applications range from uncertainty quantification to (stochastic)
PDEs, from efficient data structures to parallelizations, from error
bounds to high-dimensional applications, from dimensionality reduction
to refinement, and much more.

Abstract submission deadline: June 1, 2014

Subject: XOP-Workshop, Spain, Sep 2014

September 7-12, 2014. Workshop on "Exceptional Orthogonal Polynomials
and exact solutions in Mathematical Physics", Segovia, Spain .

Exceptional orthogonal polynomials are dense families of
Sturm-Liouville orthogonal polynomials with gaps in their degree
sequence. They appear as eigenfunctions of rational extensions of
exactly solvable potentials in quantum mechanics, and they are related
to Darboux transformations and bispectrality in the theory of
integrable systems. The past five years have seen a considerable
activity in this field and we feel the time is ripe for bringing
together many of the scientists who have contributed to this
development, and others who might be interested in them.

The list of invited speakers includes Alexander P. Veselov
(Loughborough University, UK), Robert Milson (Dalhousie University,
Canada), Antonio Durán (Universidad de Sevilla, Spain), Alexei
Zhedanov* (Donetsk Institute for Physics and Technology, Ukraine), Ryu
Sasaki (Kyoto University, Japan), Luc Vinet (Centre de Recherches
Mathématiques, Canada), Peter Clarkson (University of Kent, UK),
Manuel Mañas (Universidad Complutense, Spain), Boris Shapiro*

There will be a limited number of grants for younger
participants. Details on how to apply will be given in the website.
